·Optimization of the PDC and roller matching relationship in design.

·Selection of roller tooth profile and optimization layout of roller tooth,taking into account the aggressivenes of the roller in rock drilling,hole formation efficiency,and tooth strength and longevity,to improve the drilling efficiency and penetration rate of bybrid bits in hard formations.

·Optimization analysis of energy distribution in composite structure rock breaking,considering the matching of the lifetimes of various cutting structures.

·Hydraulic structure optimization analysis to improve the rock-carrying balance of the drill bit and the cooling efficiency of the cutting structure.
